Current research on gaze tracking, specifically relating to mouse control, is often limited to infrared cameras. Since these can be costly and unsafe to operate, inexpensive optical cameras are a viable alternative. This paper presents image processing techniques and algorithms to control a computer mouse using an optical camera. Usually, eye tracking techniques utilize cameras mounted on devices located relatively far away from the user, such as a computer monitor. However, in such cases, the techniques used to determine the direction of gaze are inaccurate due to the constraints imposed by the camera resolution in conjunction to limited size of the pupil. In order to achieve higher accuracy in pupil detection, and therefore mouse control, the camera used is head-mounted and placed near one of the user's eyes.
